Son double sets Tottenham on Chelsea's tail

Son Heung-Min struck twice as Tottenham Hotspur maintained the pressure on Premier League leaders Chelsea with a 4-0 victory against Watford at a sun-soaked White Hart Lane on Saturday.

With Antonio Conte's side not due to face Bournemouth until later in the day, Spurs made the most of the chance to close the gap at the head of the table to four points with Dele Alli and Eric Dier also on target.

The chances of Tottenham overhauling Chelsea may be slim, but manager Mauricio Pochettino can be satisfied his side are not going to give up the chase.

After recovering from a goal down to win in the final two minutes of the mid-week trip to Swansea City, Spurs did everything that was asked of them against a poor Watford side with little still to play for this season.

All four goals were the result of outstanding finishes that demonstrated the confidence running through Pochettino's side and in particular Son, who has now scored seven goals in five games.

Three first-half goals put Spurs in control and after Son added a fourth in the 54th minute, the Spurs manager brought on Harry Kane to ease the club's leading scorer back into action.

Pochettino had sprung a surprise in the build-up to this game by revealing the striker would return to the squad after recovering from an ankle injury ahead of schedule.

The Argentine opted to leave Kane on the bench and hand Vincent Janssen the chance to lead the line.

Janssen has struggled to make his mark since arriving in a £17 million ($21 million, 19.9 million euros) move from AZ Alkmaar and it quickly became clear his luck was not about to change.

The Dutchman spurned three good first-half chances before Alli finally set Spurs on their way.

Janssen's first opportunity came after just nine minutes when he turned Watford centre-back Craig Cathcart by the penalty spot and shot against the legs of goalkeeper Heurelho Gomes.

If that was unfortunate, Janssen's second miss was one he would want to forget, with the forward somehow diverting Kieran Trippier's cross onto the bar from just two yards out.
